Parameter

Description

 

 

 

 

 

 

 

 

Parameters

P20

 

Reference PF (Power Factor)

The calculated power factor to optimize the control loop.

 

 

 

 

 

 

 

 

 

P21

 

Present PF (Power Factor)

The present power factor of the motor (load).

 

 

 

 

 

 

 

 

 

P22

 

Delay Angle (SCR OFF time)

The period (in degrees) that the thyristors are in the OFF state.

 

 

 

 

 

 

 

 

 

P23

 

Maximum Optimizing Delay

Sets the maximum delay angle (max degrees that the thyristors are

 

 

 

 

 

 

 

OFF) used during the optimizing mode.

 

 

 

 

 

 

 

 

 

P24

 

Rated Current (High Byte –Hundreds)

The current rating of the soft–start set by manufacturer.

 

 

 

 

 

 

 

 

 

P25

 

Rated Current (Low Byte – Units)

The current rating of the soft–start set by manufacturer.

 

 

 

 

 

 

 

 

 

P26

 

Running Current Amps

The load current. (Always shown as phase current).

 

 

 

(RatedCurrent) x (7.96875)

 

 

 

 

 

 

 

 

 

 

 

32

 

 

 

 

P27

 

Peak Start Current (measured at last start)

The maximum current used during the last start–up.

 

 

 

 

 

 

 

Advanced Current

P28

 

Low Current Level (undercurrent trip)

Sets the under current trip level. (The low current level flag is

 

 

 

(scaling = 0.03125)

updated even if the low current trip is disabled).

 

 

 

 

 

 

 

 

P29

 

Low Current Time (delay before trip)

The number of cycles allowed for a low current level condition (P28)

 

 

 

 

 

 

 

to exist before tripping. For 60 Hz, 40 cycles = 667ms.

 

 

 

 

 

 

 

For 50 Hz, 40 cycles = 800ms.

 

 

 

 

 

 

P30

 

Current Limit Level (scaling = 0.03125)

Sets the level that the start ramp is held. (The start ramp is only held

 

 

 

 

(RatedCurrent) x (7.96875)

if the P30 value is reached. The current decreases as motor speed

 

 

 

 

 

 

increases allowing the ramp to continue).

 

 

32

 

 

 

P31

 

Current Limit Time (delay before trip)

The time allowed for start current to equal P30 value before tripping.

 

 

 

 

 

 

 

Note that for 60 Hz, 40 cycles = 667ms.

 

 

 

 

 

 

 

For 50 Hz, 40 cycles = 800ms.

 

 

 

 

 

 

P32

 

Shearpin Level (overcurrent trip)

Sets the over current trip level. Shearpin operation begins after

 

 

 

 

 

 

 

start–up is complete.

 

 

 

 

 

 

P33

 

Shearpin Time (delay before trip)

The number of cycles allowed for an overcurrent condition before

 

 

 

 

 

 

 

tripping (only when shearpin flag P51, Bit3=1). For 60 Hz, 60 cycles

 

 

 

 

 

 

 

= 1second. For 50 Hz, 50 cycles = 1second.

 

 

 

 

 

 

P34

 

Overload Level (SCR protection)

Sets the overload current level as a portion of FLA. (P34 is always

 

 

 

 

 

 

 

active but P30 is only active during motor starting.)

 

 

 

 

 

 

P35

 

Overload Delay (delay before trip)

The time allowed for an overload condition before tripping. For 60

 

 

 

 

 

 

 

Hz, 60 cycles = 1second. For 50 Hz, 50 cycles = 1second.

 

 

 

 

 

Parameters

P36

 

% Overload (status only)

The integration of the Current–Time product represented as a % of a

 

 

 

 

 

 

 

value that was preset by the manufacturer.

 

 

 

 

 

 

P37

 

Chassis Temp

The heatsink temperature. When the temperature exceeds a

 

 

 

 

 

 

 

threshold value, P37 value will change from <20 to >200.

 

 

 

 

 

 

P38

 

Pot1

The value of RV1 on the control card. 255=fully CW setting for

 

 

 

 

 

 

 

5VDC input. (Not applicable for keypad operation).

 

 

 

 

 

 

P39

 

Pot2

The value of RV2 on the control card. 255=fully CW setting for

 

 

 

 

 

 

 

5VDC input. (Not applicable for keypad operation).

 

 

 

 

 

 

P40

 

Pot3

The value of RV3 on the control card. 255=fully CW setting for

 

 

 

 

 

 

 

5VDC input. (Not applicable for keypad operation).

 

 

 

 

 

 

P41

 

DC I/P

0–12V input for load monitoring or phase angle setpoint etc.

 

 

 

 

 

 

P42

 

Thermistor

Monitors the Thermistor I/P (standard motor thermistor). The values

 

 

 

 

 

 

 

are not all that useful as thermistors act much like a switch.

 

 

 

 

 

 

P43

 

4–20mA I/P

Monitors the 4 to 20mA input. Note this input is referenced to the

 

 

 

 

 

 

 

PCB 0V and so cannot be used with daisy chained sensors.

 

 

 

 

 

 

P44

 

TEMP Trip Level

The value at which Parameter 37 causes a trip.

 

 

 

 

 

 

P45

 

4–20mA MAP

Value is the Parameter to which the 4–20mA data is sent.

 

 

 

 

 

 

P46

 

4–20mA Set Level

Value is the level at which the 4–20mA level bit will be set.

 

 

 

 

 

 

P47

 

DC Input Map

Value is parameter to which the DC input data is sent.

 

 

 

 

 

 

P48

 

Set Level DC I/P

Value is the level at which the DC–I/P level bit will be set.

 

 

 

 

 

 

P49

 

MAP DAC O/P 1

The value is the parameter that is the source for DAC 1 (0–10VDC).

 

 

 

 

 

 

P50

 

MAP DAC O/P 2

The value is the parameter that is the source for DAC 2 (0–10VDC).
